And you're sworn to secrecy

Wonderful idea. I'll definitely make one. I'm sure this isn't the only time I'll need it.

[b.lindsey]

I'll never tell  Looking forward to the  first family shot too , even if the family is still small.

Stan your engenuity just amazes me. I will be filing that one away and Marv's idea as well.  I have the plans for this engine as well so will be building it one day. Great photos and documentation as usual.

Looking good Stan!  And definitely a nice save.
Thanks for sharing your trials and tribulations with us.

Stan is THE MAN 

Nice save and thanks for sharing.

Then, with the part tilted to 18 degrees



and clamped in the vise, I milled a flat with a .125 end mill.

Then drilled until the holes met.

Hi Stan, I am always following your postings with the nicely done pictures of all your machining steps. That was an nice save also.
I need some help to understand the relationship between the drawing and final position of the oil bore.
The drawing shows an angle of 90°+18°( 18° this is not visible there  but you mentioned it)= 108°  to the centerline of the bore, 0° on the right side.
Your machining set up looks like an angle of 162° to the centerline of the bore.
Is there any misunderstanding from my side ?

The critical dimension here is the hole entry into the bore.
Jerry Howell's detail is here



In fact, after I made a flat with the .125 end mill, the drill bit kept sliding off. I increased the angle until the drill stayed in position. The 2.530 dimension is also used to drill the cylinder's oil hole so it will align with the hole in the bore, shown here



I try to look at a drawing and determine what is a critical dimension and what needs to be "pretty close"

[fumopuc]

Hi Stan, I try to let you know by a simple modified picture what I have in my mind.
If you do a set up for the 18° bore like described in the drawing it should be in this way ?
Or may be I have had to much beer last evening and I am totally wrong.
Anyway,  I like your build and will following along.

Achim
Based on your beautiful work, I'm sure you're correct. My concern was to have the entrance hole in the correct position and to have it meet the other hole. They did, so I'm OK with it. Probably not precisely correct but as long as oil comes out of the hole in the cylinder sleeve, functionally it's correct and not visible.

Hi Stan I am glad now, because it was only one beer last night.
To be honest, I have been with this issue also minimum two times in conflict during the last two years.
Have a nice Sunday, my one is already nearly gone.

Amazingly, nothing went awry with the remainder of the water hopper machining.

There were three operations to complete this part: Rounding the bottom; boring a hole for the water and turning the water funnel.

I turned a piece of cold rolled to be a slip fit and clamped the part in the vise. Then, removing metal with a hogging end mill, a slight turn and more hogging until the part was close to round.







Then, filing and sanding to smooth the curved botton.



The part was returned to the mill and leveled to bore the hole for the water.



After step drilling and then a 1” end mill, the recess was completed with the boring head.





A recess .170 deep was next to receive the funnel.



Now to the lathe to fit a 6061 round into the recess. This part will be the funnel.



With the compound at 20 degrees, the taper was turned and then the round insert bit to create a cove.



A .75” hole was drilled and then the compound at the same 20 degree angle to bore the inside taper.



The finished funnel.



In place. I’ll do a bit of filing to reduce the base thickness until it’s flush with the hopper body. Then Loctite.



That really does complete the water hopper. Next is the frame front half and then some assembly of the frame and water hopper.

Looking great Stan...glad today went without mishaps too. It looks bigger in your hand than I was expecting but could just be the picture.

Damn Vern, that's looking good.  All that rounding and blending,  I swear you may grow up to be another George Britnell.

It's not a small engine, especially with those 2 big flywheels.

Rev
Not enough years to even approach George. But thanx
